Product Description
True RMS AC current me-
tering transformer for 25, 50,
100, 250 or 500 AAC. Out-
put current in accordance
with IEC 60381-1 (A 82-10,
A 82-20) or output voltage in
accordance with IEC 60381-2
(A 82-30).
A 82-10 and A 82-20 can be
used with relays DIB01,
PIB01, DIC01 or PIC01.
A 82-30 can be used with
DUB01, PUB01, DUB71,
DUC01 or PUC01.
All units can be directly con-
nected to a PLC. Power
supply ON is indicated by a
green LED on the side of the
housing.

A 82-10 and A 82-20 ar
e
true RMS current metering
transformers with standard
source/sink output 0-20 mA /
4-20 mA, whereas A 82-30
is a metering tranformer with
0-10 VDC output voltage.
This makes them very useful
as an AC cur
rent interface to
a PLC with mADC or VDC
input. Used with relays
DIB01, PIB01, DIC01, PIC01
(A 82-10, A 82-20) or
DUB01, PUB01, DUB71,
DUC01, PUC01 (A 82-30),
one or mor
e setpoints can
monitor the current and sig-
nal alar
m.
The meter
ed conductor is
drawn through the central
hole of the current metering
transformer. It is possible to
meter currents below the
nominal range by drawing
the conductor thr
ough the
hole several times. If the
conductor is drawn thr
ough
the central hole e.g. 5 times,
the transformer will register
50 A when the current in the
conductor is 10 A.
